Latest developments in fast tool servo technology

In person: 21 October 2021 • 9:00 AM - 9:20 AM EDT | Highland A


We report on the latest developments in fast tool servo technology for cutting freeform surfaces and lenslet arrays. Fast tool servo cutting performance is examined and contrasted to micro-milling and XZC turning for low spatial frequency surfaces and high spatial frequency surfaces (e.g. lens arrays). The influences of servo bandwidth, positioning resolution, and vibration level are examined in terms of their effect on form accuracy, mid-spatial frequency errors, surface finish and cutting time.

Jeffrey Roblee joined Ametek Precitech in February, 2002 and is now a Divisional Vice-President of Technology. Dr. Roblee began his engineering career at Lawrence Livermore National Laboratory in 1977. There he developed ultra-precision machine tools and measuring instruments for use in optics fabrication. His research work continued at Philips Research Laboratory in Holland in 1986 and at Carl Zeiss in Germany in 1990. In late 1993 Dr. Roblee joined the Optical Engineering Department at Polaroid where he led a program to develop a laser print head for medical images and was involved in many optical fabrication projects. By 2001 he was a Technical Director leading 4 departments. Dr. Roblee has presented numerous papers on temperature control, machine dynamics, air bearings, and optics fabrication. From 2007 to 2009, he served as a member of the Board of ASPE and as President in 2008. He has an MS and PhD, both in mechanical engineering, from the University of California at Berkeley
